## Discrepancy

(CAN) NR 2 AND  NR 4 CYLINDER VALVES WERE NOT OPERATING, INVESTIGATION FOUND THE FRONT CAM LOBES WERE MISSING.  THE CAM WAS REPLACED AND SO WERE THE NR 2 AND NR 4 CYLINDERS.  THE ENGINE WAS RETURNED TO SERVICE.  AFTER 77 HOURS OF OPERATION, THE REAR CAM LOBES WERE WORN AWAY.  THE ENGINE WAS REPLACED AND SENT FOR OVERHAUL.
